A dike is tabular, intrusive, igneous rock that cuts across the layering of adjacent rock, intrudes into an existing fracture, or creates a new fracture by forcing its way through pre-existing rock.

A sheet or wall-like mass of igneous rock that cuts across other rocks.

Dike - A tabular (book-shaped) igneous intrusion that cuts across the bedding of older rock.

a tabular (table-top-shaped) body of igneous rock that cuts across the struc-ture of the country rocks. It is a discordant igneous intrusion.

A dike is a long and narrow (tabular, like a table top) "discordant" magmatic intrusion; dikes cut across local sediment and rock layers. Back

A discordant pluton that is substantially wider than it is thick. Dikes are often steeply inclined or nearly vertical. See also sill. dilatancy The expansion of a rock's volume caused by stress and deformation.

Figure A dike is an intrusive igneous body that cuts across the grain of the rock it intrudes. Compare sill.

A tabular intrusive rock that cuts across strata or other structural features of the surrounding rock.

volcanic rock entering the bedrock perpendicular.

A tabular igneous intrusion that cuts across the host bedrock.

A long, narrow and more or less vertical mass of igneous or eruptive rock intruded into a fissure of surrounding older rock.

a rock structure caused when solid rock cracks and molten rock from the magma below is forced up through the crack and then solidifies

a sheetlike body that fills a fracture that cuts across other rocks

a tabular body of igneous rock cutting across bedding and hence, discordant

a tabular or sheet-like discordant igneous rock body

a tabular (shaped like a wall) usually vertical to nearly vertical intrusive igneous body that cuts through existing rocks

a vertical or near vertical intrusive igneous rock igneous rock body that cuts across the rock beds

A tabular body of rock hardened from a molten state (igneous intrusion) that has cut across the bedding or alignment of the surrounding rock.

It is a term given to the wall of igneous rock which cuts across layers of surrounding rock.

A sheetlike body of igneous rock that cuts across layering or contacts in the rock into which it intrudes.

A sheet-like or tabular-shaped igneous intrusion that cuts across the sedimentary layering, metamorphic foliation, or other texture of a pre-existing rock. more details...

a tabular or sheetlike body of igneous rock that cuts across the structure of adjacent rocks into which it intrudes.

A tabular body of igneous or lava rock that cuts across adjacent rocks or cuts massive rock.

A tabular (wall-shaped) intrusion of rock that cuts across the layering of country rock.

A dike is a sheet-like intrusion of magma (molten rock) that froces its way through a layer of fractured rock. The magma flows through cracks in the rock and later cools and solidifies into a sheet of igneous rock.

a volcanic intrusive rock perpendicular to dominant stratigraphy.

A tabular body of igneous rock that cuts across the structure of adjacent rocks or cuts through massive rocks. Chasm View in the Black Canyon of the Gunnison, Colorado, exposes some good examples of dikes.

An igneous intrusion that cuts across the bedding of the country rock;

An embankment of earth and rock; especially, a levee built to hold water.

geologic structure deriving from fracture filled by foreign material and younger than country rocks.

A long, narrow body (like a table top on its side) that cuts into cooler rocks.

Rising magma cooling underground which cuts vertically across exisiting rock. Dikes and sills of Keweenawan time arose among the older Rove Formation which runs from Gunflint Lake east to Superior (our BWCA Region V). More resistant to erosion and glaciation than the surrounding rock, they delineate the long and narrow lakes which are the hallmark of this region.

a long mass of igneous rock that was intruded into a crosscutting fissure in older rock; a discordant intrusive body of tabular rock. [AHDOS

A tabular igneous intrusion that cuts across structures of surrounding rock. (See also Discordant intrusion.)

A dike or dyke in geology refers to an intrusive igneous body. The thickness is usually much smaller than the other two dimensions. Thickness can vary from sub-centimeter scale to many meters in thickness and the lateral dimensions can extend over many kilometers.

an earthen embankment constructed to retain floodwater; when used in conjunction with a bridge, it prevents stream erosion and localized scour and/ or so directs the stream current such that debris does not accumulate; also known as dyke; see SPUR DIKE

Usually an earthen structure alongside canals and rivers to maintain water within the watercourse. Sometimes submerged in the watercourse to control water flow. Digue in French.

an embankment of earth or rock built on a levee to prevent floods

a wall or mound built around a low-lying area to prevent flooding. Sometimes called a berm or levee.

a barrier constructed to contain the flow of water or to keep out the sea

a huge wall that blocks storm water from flooding towns around a lake or body of water

an embankment constructed of earth or other suitable materials to protect land against overflow from streams, lakes, or tidal influences or to protect flat land areas from diffused surface water

an embankment, wall, fill, piling, pump, gate, floodbox, pipe, sluice, culvert, canal, ditch, drain, or any other thing that is constructed, assembled or installed to prevent the flooding of land

a permanent or temporary wall along a river's bank to prevent flooding

A bank (usually earthen) constructed to control or confine water.

A long, low embankment. The height is usually less than four to five meters and the lenghth more than ten or fifteen times the maximum height.

An impermeable or semi-permeable linear structure for the control or containment of overbank flow. A dike-trending parallel with a streambank differs from a levee in that it extends for a much shorter distance along the bank, and it may be surrounded by water during floods.

A barrier blocking a passage, especially for protection.

Bank of earth or stone used to form a barrier, frequently and confusingly interchanged with levee. A dike restrains water within an area that normally is flooded. See levee.

An impervious barrier to control movement of water.

In most areas of the U.S., an earthen structure built partway across a river for the purpose of maintaining a navigation channel. In other areas the term is used synonymously with levee.

an artificial watercourse; a bank usually of earth constructed to control or confine water, such as a levee

A vertically oriented barrier used in the molding process which delineates the margins of the portion currently being made of a multi-piece mold. Usually made of plastilina or cardboard.

Sometimes written as dyke; earth structure along a SEA or RIVER in order to protect LITTORAL lands from flooding by high water; dikes along RIVERS are sometimes called LEVEES.

An embankment to confine or control water. Often built along the banks of a river to prevent overflow of lowlands: a levee.

Also levee; an embankment used to confine or control water. Dikes are often built along the banks of a river to prevent overflow.

(1) Usually an earthen bank alongside and parallel with a river or open channel to restrict overflow (See Levee).  (2) An asphalt concrete berm along the edge of a shoulder.

underground water barrier formed of nonporous, dense volcanic bedrock (basalt); can form water storage chambers

A barrier constructed to control or confine hazardous substances and prevent them from entering sewers, ditches, streams, or other flowing waters.

A raised bank, typically earthen, constructed along a waterway to impound the water and to prevent flooding.

a barrier usually made of earth, which runs alongside a river to keep it from overflowing at high water

Barrier constructed to hold back a spill or leak.

1. An embankment or dam made to prevent flooding by a body of water. 2. A protective barrier.

A low wall that can act as a barrier to prevent a spill from spreading.

A physical barrier used as a defense against the flowing of a liquid material into the environment. Refers to concrete, earth, and other barriers temporarily constructed to hold back the spill or leak. See Dam.
